The Whenuakura bridge crosses the Whenuakura River between Rangikura and Patea, on the Marton-New Plymouth section.
Massive Concrete Piers.
Another view of the new Whenuakura bridge shewing the foundation work nearing completion.
The new bridge will have a main steel truss span of 142ft. and three 60ft. steel plate girder spans. The main piers will be constructed by sinking 10ft. diameter reinforced concrete cylinders and driving piles inside the cylinders. The shore pier at the south end is to be of mass concrete also on a piled foundation, while the abutments are a combination of mass concrete and reinforced concrete construction, piling being dispensed with, and the foundation load distributed over a large area by means of a reinforced concrete raft.
The formation of the approaches to the new bridge has been completed, and the contractors for the construction of the bridge, Messrs. Bird and Codling, are making good progress with the foundation work, being now ready to proceed with the erection of the superstructure.
